In my experience, battery life is hard to compare. Sometimes I have 50% battery left after about 16 hours and sometimes I have 20%. I think it depends on how long I am connected to WiFi, how good the coverage is and how often I use the phone. If I answer a lot of messages and calls, the battery life is much worse than if I leave the phone alone for a few hours. If the phone is left unattended over the weekend, two days of battery life is still possible. I generally use the phone without any play services, with Signal, FairEmail, Threema, Conversations and KDE Connect running all the time.
Edit: Android 14 (P6a) improved my battery life in general. A rough guess would be about 10-15%.
